DETAOHABLE-JAW TOOL.

Specification of Letters Patent.

Patented Aug. 3, 1909.

Application filed September 17, 1908. Serial No. 41,53,529.

Be it known that l pakoneta, in the county of Auglaize and State ofOhio, have i vented certain new and useful improvements in Detachable-Jaw Tools; and I do declare the following to a full, clear, and exactdescri tion oi the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in pivoted tools, and comprisesthe production of a pivotal tool provided with means for removablysecuring jaws thereto.

One of the objects of the invention is the production of a pivotal toolformed with locking means for securing thereto ditlerently-eonstructedremovable jaws.

Another object of the invention is the production of a removable jaw forpivotal tools adapted to be readily secured to a speciallydesigned toolby a simple spring locking arrangement.

lVith these and other objects in view, the invention consists of certainnovel features of construction, combination and arrangementof parts aswill be described and par ticularly pointed out in the appended claims,and in the drawings, in which- Figure 1 is a perspective view or" myiin-- proved tool; Fig. 2 is a fragmentary longitudinal sectional viewthereof; 3 is a transverse sectional view taken on the line 3-3 of Fig.2; Fig. i is a transverse sectional view taken on the line li of F 2;Fig. 5 is a detail perspective view of a re movable jaw; Fig. 5 is adetail perspective view of a set of removable jaws formed with a sidecutting edge; Fig. 7 is a detail perspective view of an end cutting jaw;Fig. 8 is a detail perspective view of a wiredornr ing tool or jaw; 9 isa detail perspective view of an end-receiving gripping jaw; Fig. 10 is adetail perspective view of a side-re ceiving gripping aw; and Fig. 11 isa detail perspective view of a doubly-channeled gripping aw.

Corresponding and like parts are referred to in the followingdescription and in all of the views of the drawings by the samereference characters.

In the drawings, 1 and 2, denote pivotal members, which are formed withjaw-carrying ends 3 and 4. A plurality of lateral 1 l Lani. L. MUELLER,a I citizen oi the United States, res1d1ng at Wapins, 5 and 3, projecttoward each other from the ends 3 and J1, and said pins are formed withcross heads, 7 and S. The pins, 5 and 6, are positioned midway oi theends, 3 and i, and are recessed at their outer ends to receive the endo1 fiat springs, 9 and 10. The spring 9 and 10, are seated inlongitudinal slots, 11 and 12, and extend to the terminals 0. the ends,3 and lit; a point midway of their ends, the springs, 11 and 12, areconnected to movable pins, and 14, which extend through openings, 15 and16 formed in the jaw-carrying ends, 3 and -l-, and project interiorly ofthe inner faces of said jawcarrying ends. The pins, it and 13 areslightly rounded on their inner ends and are adapted to projectthroughopenings, 17, formed in a removable jaw, 18. The removable aw, 16, isslightly beveled on its sides at 19 and is formed with a reduced end,20, having an opening, 21, formed therein, said opening beingsubstantially circular in its middle body portion and rectangular at itsends.

The removable jaw, 18, may be readily secured to the jaw-carrying ends,3 and i, by passing the reduced end, 20, over the pin, 6 and turningsaid jaw on said pin so that the opening, 1?, in said jaw will registerwith the inwaall oro ectine end of the t pins, 13 and 14,-. W hensecured in place on the jaw-carrying ends, 3 and a, the removable jaw 18will be rigidly loc red in place by means of the cross heads ffl'l'LiOClon the pins, and t3, and the pins 15 and 16, and cannot, of itself, -cdisengaged from aid jaw-carrying ends or turn upon the connecting pins.The springs, 11 and 12, normally press the pins, 18, 1 t, inwardlythrough the openings formed in the removable jaws and the lateral pins 5and 6, which, when provided with the cross heads 7 and 8, aresubstantially l -shaped in cross section, may he formed integral withsaid jaws or threaded thereon.

The removable jaw illustrated in Fig. 5 is termed substantially tlat andthe beveled ec ges, 19, of said jaw are adapted to engage tne roundedends or the lateral pins, 5 and 6, in such manner that the turning ofthe removable jaws, 18, upon the T-head pins 5 and 6 will force the pins18 and 14 outwardly so that the said jaw may readily 0ccupy its lockedposition.

The removable jaw illustrated in Fig. 6 is substantially the same astheaw illustrated in Fig. 5, and designated in the description by thenumeral, 18, with the exception that the face of said jaw is formedsmooth and is provided with a laterally-projecting edge, 22, which isadapted to engage a similarlyformed edge on an opposing removable jaw.hen secured in place, a pair of the removable jaws illustrated in Fig.(3 is adapted to make a scissors cut in the material to be operated on.

The removable jaw illustrated in Fig. 7 is similar to the awsillustrated in Fig. 6, with the exception that the cutting edge isformed on the end of said jaw, and the cutting edges of two aws move to*ard each other with an evenly-opposing movement.

The removable jaw illustrated in Fig. 8 is formed with a rounded end andis particularly adapted to enable an operator to quickly form wires intovarious shapes, as by twisting and turning.

The removable jaw illustrated in Fig. 9 is longitudinally curved andformed with a plurality of ridges or corrugations and is adapted toreceive round material through the end of said jaw.

In Fig. 10 a removable jaw is illustrated, which is similarly formed tothe jaw shown in Fig. 9, with the exception that the groove extendslaterally across the end of said aw instead of longitudinally therewith.

In Fig. 11 is illustrated a removable jaw formed with double channelswhich are shown to extend laterally across the end of said jaw, but asis obvious, may be arranged to extend longitudinally therewith.

It will be seen that by means 01' my invention a pivoted tool isprovided which may be adapted for a wide field of use, and may be usedfor cutting and gripping differentlyshaped articles. It is also obviousthat the differently-formed removable jaws may be quickly secured to thepivotal tool ends, 3 and 4-, and quickly removed therefrom.

From the foregoing description, taken in connection with theaccompanying drawing, the construction and operation of the inventionwill. be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention as defined in theappended claims.

Having thus described my invention, what I claim. as new and desire tosecure by Letters-Patent, is:

1. A pivotal tool having one of its ends provided with an inwardlyfacing T-headed pin and a lateral sliding pin resiliently forced inwardon said end in combination with a jaw removably secured to the pins andsaid end.

2. The combination with a pivotal tool formed with a lateral pin, etaremovable jaw formed with an opening arranged to receive the lateralpin, and resilient means for looking the removable aw to said pin.

3. The combination with a pivotal tool formed with a T-headed lateralpin, and a resiliently controlled projecting pin, of a removable jawarranged to be secured in locked position on said pins.

l. The combination with a pivotal tool formed with a plurality ofopposing T- headed pins, and a plurality of longitudinal slots, springsseated in the longitudinal slots, pins secured to the springs slidablvextending througi he pivotal tool, removable jaws formed with openingsto receive the ends of the pins, and means for locking the removablejaws to the pins.

The combination with a pivotal tool formed with plurality of projectingT- headed pins and provided with resilientlycontrolled laterally-slidingpins, and of a plurality of opposing jaws removably secured to the endsof the tool and in locked position on the pins.

6. The combination with a pivotal tool formed with a plurality ofopposing T- headed pins, plurality of removable jaws formed withopenings corresponding to the form of the heads of the pins, a pluralityof spring controlled laterally sliding pins arranged to project throughopenings formed in the removable jaws, and means for looking theremovable jaws to the tool.

7. The combination. with a pivotal tool formed of a plurality oflaterally-projecting pins formed with cross pieces, a plurality ofsprii'ig-controlled laterally-sliding p1ns, and a plurality of jawsformed with openings adapted to receive the pins and arranged to besecured in locked position thereon.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
